Risk Evaluation of Workers Exposure to Magnetic Fields in Indoor Distribution Substations

Due to possible health effects of electric and magnetic fields, a directive on minimum health and safety requirements regarding the exposure of workers to electromagnetic fields has been disposed by European Parliament and Council regarding the exposure of workers to electromagnetic fields. This legislation will be nationally implemented in 2012.The aim of this work was to develop a electromagnetic field exposure measurement method and further a magnetic field hazard evaluation method for exposure of workers in indoor medium to low voltage （MV/LV） distribution substations. Magnetic field exposure was also reflected with BS 8800 general risk classification procedure to accomplish specifications to execute magnetic field measurements and carry our risk assessment procedure for working tasks. The risk assessment procedure is based on magnetic field exposure measurements and dosimetric FEM calculations founded on EU Directive 2004/40/EC. According to field measurements action values were exceeded in several working tasks but limit values were not exceeded.
